    Description / Table of Contents: Phosphorpentoxid in der Organischen Synthese, VII. - Synthese von 3-Aryl-3,7-dihydro-4H-pyrrolo[2,3-d]pyrimidin-4-iminenDurch Umsetzung von 2-(Acetylamino)-3-pyrrolcarbonitrilen 1 mit einer Mischung von Phosphorpentoxid, N,N-Dimethylcyclohexanamin und einem geeigneten Arylamin-hydrochlorid bei 150-180 °C werden die Titelverbindungen 2 erhalten. Das verwendete Arylamin-hydrochlorid muß absolut wasserfrei sein, da anderenfalls 4-(Arylamino)pyrrolo[2,3-d]pyrimidine 4 als Nebenprodukte entstehen können. - Die Ergebnisse der Prüfung auf Pestizid- und Antikrebs-Wirksamkeit werden mitgeteilt.
    Notes: The title compounds 2 were prepared by treating 2-(acetylamino)-3-pyrrolecarbonitriles 1 with a mixture of phosphorus pentoxide, N,N-dimethylcyclohexanamine, and an appropriate arylamine hydrochloride at 150-180°C. The importance of using absolutely anhydrous arylamine hydrochlorides is stressed because failing this, 4-(arylamino)pyrrolo[2,3-d]pyrimidines 4 can be formed as by-products. - The results from pesticide and anticancer screenings are reported.
